In ngx_http_gzip_header_filter there is a call to ngx_http_clear_etag.
While this spec-compliant it loses the benefits of etags. Two
alternate approaches would be:
- Only clear the etag if it's strong.
- Append ";gzip" to the etag, remove it from
incoming "if-none-match" requests.
Would a patch to implement one of these be welcome?
